The Apple TV ($99) is a must have for power iTunes users. Movies and TV shows from the iTunes Store — plus Netflix, Hulu Plus, YouTube, Vimeo, and live MLB, NBA, and NHL games — can be played back on your HD display in top-notch 1080p. The media library isn't as big as Roku's, but if you already have rich content on your Mac or PC that you share often, like photo libraries and home videos, you've met your match with Apple TV.
